DEVICE AND METHOD FOR PRODUCING AND MONITORING A SAFETY AREA IN A WORK SPACE

摘要

The application relates to a device (1) for generating and monitoring a security area (2) in a work area (3). The proposed device (1) comprises a receiving device (4). The recording device (4) is set up to record images in a monitoring area (8) comprising the security area (2). Furthermore, the device (1) comprises an illumination device (5) which is set up to project lines (6) or patterns defining the security area (2) into the work space (3). The device (1) also includes an evaluation device (9) which is set up to evaluate the images recorded by the recording device (4) with regard to a violation of the security area (2). The lighting device (5) is designed to project a time-coded sequence (11, 11 ', 11 ", 11"', 11 "" ') of the lines (6) or patterns into the work space (3). In addition, the evaluation device (9) is set up to compare images of the time-coded sequence (11, 11 ', 11 ", 11"', 11 "" ') of the lines (6) or patterns with an expected sequence and to output an injury signal , if the images of the time-coded sequence (11, 11 ', 11 ", 11"', 11 "" ') do not match the expected sequence.
